I don't think there's any architecture where this is true.  The
opposite is true in a 64-bit Windows build (which isn't my case).  But
I don't think I ever saw a size_t that is narrower than a long.

I'm quite sure this crash is related to the version mbrtowc we have in
xspara.c, I just need to devise a way to catch it.  Unfortunately,
using fprintf and sprintf cause compilation errors there...
